[0002] In the prior art, a tunnel excavation and crushing vehicle has a mechanical arm assembly with a breaker hammer installed at the front end of the vehicle body so that the mechanical arm assembly has a larger rotation space. However, this method causes the overall length of the crushing vehicle to be longer, and the length of the chassis assembly of the vehicle to be longer, which in turn increases the cost of the vehicle. The end or side wall of the crushing piece in the prior art is connected to the mechanical arm assembly by a hinged manner, so that the shear force of the crushing piece body is larger and the stress is more concentrated, and the range of vertical crushing that the crushing piece in the prior art can perform on the face is limited, so there is room for improvement.

At the same time, through the functional design of the mechanical arm assembly and the crushing parts, the total vehicle has a larger range of vertical crushing on the face, and can also realize rapid adjustment of the position of the crushing parts, reduce equipment movement time, and improve crushing efficiency and crushing force.

[0004] In summary, in order to optimize the overall layout of the tunnel excavation and crushing vehicle, increase the range of vertical crushing that the tunnel excavation and crushing vehicle can perform on the tunnel face, and improve the crushing effect of the tunnel excavation and crushing vehicle, the present application proposes a tunnel excavation and crushing vehicle.

[0043] The second rotary mechanism 6 includes a rotary component 7 and a rotating table 8. The rotary component 7 is bolted to the swing seat 19. The rotary mechanism includes a power source. The power source drives the rotary component 77 to rotate, so that the rotary component 7 can rotate on the vertical plane. The rotating table 8 has a corner 9. The rotating table 8 is "L" shaped. The right end of the rotating table 8 is bolted to the left end of the rotary component 7, so that the rotating table 8 rotates as the rotary component 7 rotates. The upper end of the rotating table 8 is bolted to the crushing component 2, so that when the rotary component 7 rotates, the crushing component 2 rotates around the rotary component 7 as the rotary component 7 rotates.

[0044] The crushing component 2 includes a propulsion slide 10, a breaker hammer 11 and a propulsion cylinder 12.

[0045] By providing a groove 26 at the lower part of the cab 23, the mechanical arm assembly 1 is partially placed in the groove 26, thereby compressing the total length of the cab 23 and the mechanical arm assembly 1, and by the crushing part 2 being parallel to the slewing assembly 7, and part of the crushing part 2 being located above or behind the slewing assembly 7, the overlap range of the crushing part 2 and the slewing assembly 7 is large, thereby shortening the length of the crushing part 2 and the mechanical arm assembly 1 compared with the prior art, thereby greatly shortening the total length of the total vehicle for tunnel excavation and crushing compared with the prior art, and the total vehicle structure is compact, thereby The performance of the chassis assembly 22 required by the total vehicle is relatively stable, the cost is relatively low, etc. The total vehicle for roadway excavation and crushing makes the crushing element 2 parallel to the axial direction of the second rotary mechanism 6 through the rotating table 8 with the corner 9, that is, the crushing element 2 is normally perpendicular to the tunnel face, so that the total vehicle for roadway excavation and crushing has more convenient vertical crushing of the tunnel face than the general crushing mechanism, and the crushing element 2 is eccentrically arranged on the second rotary mechanism 6, so that the crushing element 2 has a larger range for vertical crushing of the tunnel face, and the crushing element 2 can be very convenient to perform vertical crushing. The tunnel excavation and crushing vehicle can also move the crushing element 2 perpendicular to the tunnel face on the horizontal axis through the cooperation of the first slewing mechanism 3 and the swing mechanism 5, and can also move perpendicular to the tunnel face on the vertical axis through the first pitching mechanism 13 and the second pitching mechanism 14, so that the tunnel excavation and crushing vehicle has a larger range of crushing perpendicular to the tunnel face, and it is more convenient to move the crushing element 2 perpendicular to the tunnel face; at the same time, the crushing element 2 allows the breaker 11 to move perpendicular to the tunnel face on the thrust slide. The push slide 10 can be slid and retracted on the rotary table 8. When the breaker 11 makes the face uneven, the breaker 11 can be deeply crushed by retracting the propulsion cylinder 12. The deep crushing can be conveniently completed without the movement of the trolley, which is beneficial to improving the crushing efficiency of the crushing work. The bolt connection between the push slide 10 and the rotary table 8 effectively strengthens the connection effect between the push slide 10 and the rotary table 8, and there is no rotating connection between the push slide 10 and the rotary table 8, which reduces the damage of shear force and other stresses on the push slide 10, making the performance of the total vehicle for tunnel excavation and crushing more stable.

One end of the swivel cylinder 40 is connected to the swivel seat, and the other end is connected to the vehicle body, so that the swivel cylinder 40 can be extended and retracted to drive the swivel seat to perform a swivel and swinging motion, which is suitable for situations where the first swivel mechanism 3 is not required to have a too large swing range.

[0051] Furthermore, in this embodiment, the rotary cylinder 40 is connected to the oil circuit of the third cylinder 20 of the swing mechanism 5, so that when the swing cylinder drives the swing seat 19 to swing to the left, the rotary cylinder 40 drives the swing seat to move to the right, thereby allowing the crushing mechanism assembly 25 to self-adjust, so that the breaker 11 is always perpendicular to the face to be crushed.
